What is Froxlor?

Seven consecutive security releases as froxlor works through an input-validation audit.

Every froxlor release since February has been titled a security release, and the pattern inside them is consistent: batches of validation fixes across the API and frontend rather than responses to single disclosures. The work covers DNS record content validation across LOC, RP, SSHFP, TLSA, NAPTR and TXT types, path traversal and symlink resolution in data export and authorized_keys handling, ownership checks in email and domain operations, CSRF tokens on AJAX actions, and requiring the current password before generating an API key. The June sequence — 2.3.8, then 2.3.9 and 2.3.10 the same day — shows a regression being chased immediately after a fix.

What is Slurm?

Slurm 26.05 makes SLUID the default job identity and pulls TLS into the daemons.

Slurm is maintaining three branches concurrently — 26.05 as the new major line, 25.11 as the stable one, and 25.05 still receiving fixes — and releases them in same-minute pairs. The 26.05 line introduces SLUID as the default identifier used in cgroup paths and step lookups, and a tls/s2n path with a certgen plugin for generating step certificates. Everything else in this window is correctness work: controller crashes under load, shutdown and reconfigure races, memory leaks in slurmstepd and slurmrestd, and cross-version compatibility between mismatched daemons.

Seven consecutive security releases as froxlor works through an input-validation audit.

◆ Current state

Every froxlor release since February has been titled a security release, and the pattern inside them is consistent: batches of validation fixes across the API and frontend rather than responses to single disclosures. The work covers DNS record content validation across LOC, RP, SSHFP, TLSA, NAPTR and TXT types, path traversal and symlink resolution in data export and authorized_keys handling, ownership checks in email and domain operations, CSRF tokens on AJAX actions, and requiring the current password before generating an API key. The June sequence — 2.3.8, then 2.3.9 and 2.3.10 the same day — shows a regression being chased immediately after a fix.

◆ Where it's heading

This reads as a systematic audit being worked through in order rather than incident response. The fixes group by class — first DNS record content, then path and symlink containment, then ownership and authorisation checks, then CSRF and response filtering — which is what a methodical pass over a hosting control panel's attack surface looks like. A control panel is an unusually high-value target since it holds root-adjacent capability over customer domains, mail and databases, so the concentration on ownership validation and path containment is well aimed. Feature work is essentially absent; the non-security content is translations and dependency bumps.

◆ Prediction

Expect the security-release cadence to continue until the audit is exhausted, with the remaining validation surface — likely the config-service and task-generation paths — as the next area. The same-day 2.3.9 and 2.3.10 sequence suggests the team will keep shipping fast follow-ups rather than batching regressions into the next monthly release.

5.0

Slurm 26.05 makes SLUID the default job identity and pulls TLS into the daemons.

◆ Current state

Slurm is maintaining three branches concurrently — 26.05 as the new major line, 25.11 as the stable one, and 25.05 still receiving fixes — and releases them in same-minute pairs. The 26.05 line introduces SLUID as the default identifier used in cgroup paths and step lookups, and a tls/s2n path with a certgen plugin for generating step certificates. Everything else in this window is correctness work: controller crashes under load, shutdown and reconfigure races, memory leaks in slurmstepd and slurmrestd, and cross-version compatibility between mismatched daemons.

◆ Where it's heading

The bulk of the engineering effort visible here goes to concurrency and lifecycle correctness in slurmctld — races between the purge thread and job/node write locks, accounting_storage callers racing plugin teardown, connection plugin initialization ordering, forwarding threads outliving shutdown. That is the profile of a codebase being hardened for larger and busier clusters rather than one adding scheduling features. The second thread is upgrade tolerance: multiple fixes exist purely to keep a 26.05 slurmd working with a 24.11 sattach or a 25.05 slurmstepd, which tells you how staged real site upgrades are.

◆ Prediction

Expect 26.05.x to keep issuing fixes for the SLUID transition and for mixed-version daemon combinations, since both are where this window's regressions cluster. The 25.05 line looks close to the end of its fix stream, with its recent releases limited to shutdown races and build compatibility.
